You are wrong: this IS RED Dawn. No less an invasion than if Russkie paratroopers fell out of the sky. Whose flags are these invaders carrying? Mexican and Red (Communist) flags. What is the difference if we lose our country to Soviets carrying AK47 or to Illegal immigrants carrying the Mexican flag? Either way it's gone.
The paratroopers in the film were Cubano, Nicaraguan and other Hispanic-speaking proxies. The secret police advisors and their bodyguards were Russian.
